top·sy-tur·vy – the feeling you get in your stomach when that special someone you’ve been staring at for months notices you for the first time and smiles. Or, the feeling you get in your stomach after licking the underside of a public toilet seat.

I like it, but the leveldesign goes from being tricky to figure out to being tricky to complete. Some of the middle levels boggle your mind a bit but then it turns into a standard "dodge 1 million dangerous obstacles" platformer.
